…Functions / …Bank Control
…Bank Control Using First In First Out (FIFO) and Rotate modes on a 3 pump system
Bank Size Select the number of stages (pumps) required for the application from 2 to 6 or Off.
Off disables the Bank Control functionality.
Control Source Select the analog signal to act as the control signal for the bank control.
This is normally the Process Variable (PV) for most pump control applications.
Stage 1 (6)
Off Trip
Select the Control Source value (PV) at which the output (pump) is turned off.
On Trip
Select the Control Source value (PV) at which the output (pump) is turned on.
Output
Select the initial output (relay or digital output) that the output is assigned to by
default (for example, when FIFO or Rotate mode is not in operation).
Schedule
Select the wear levelling schedule required:
Off – the output is not controlled by the bank schedule.
The state of the output is controlled entirely by its associated trip points.
FIFO – the output is controlled according to the FIFO schedule mode.
Rotate – the output is controlled according to the Rotate schedule mode.
